"I started getting the guilt of 'Maybe I did something wring, put them in a wrong position, or did something like that,'" said Chugg.

Chris's son Randy, also a veteran, took his own life.

"I felt like I should have done more...and intervened more. Because there was something wrong," said Chugg.

Then there's Army Veteran Jeremy Anderson, also from Warrensburg. He also attempted to take his own life.

"It's pretty rough," said Anderson.

The Department of Defense and Veterans Administration report more than 100 active service members died by suicide from April to June 2017.

"I was also second-guessing myself of what I could have done different," said Chugg.

Experts call this "moral injury."

"It may be a situation where they're forced or faced with having to make moral and ethical decisions on life and death," said Dr. Briana Nelson Goff, Director of the Kansas State University Institute for the Health & Security of Military Families.

Dr. Goff says a combination of factors leads to suicide. These include repeated combat deployments, recruits joining from traumatic backgrounds, problems transitioning to civilian life, and how PTSD is being treated.

"We're treating it as a mental illness, which is how it's identified, but it really needs to be understood as a systemic illness. As an illness that has physical effects, it has mental effects, but it also has interpersonal effects as well," said Goff.

She says the best way to help veterans, and for veterans to help themselves, is to do what Chugg and Anderson did.
